Flood Insurance Rate Maps (FIRMs) and the Flood Insurance Study (FlS) for Sutter County
The Federal Emergency Management Agency (FEMA) produces and continuously updates flood hazard data in support of the
National Flood Insurance Program (NFIP). In July of 2015 FEMA issued an updated Flood Insurance Study (FIS) for
Sutter County (Unincorporated Areas) and also issued new FIRMs for the Natomas Basin designating most of the basin
as A99. After Natomas Basin levee improvements are completed and the levees are recertified FEMA will remap the
Natomas Basin and the A99 areas will be changed to X Zones. Because of current design and construction progress on
Sutter County levee systems the County does not anticipate any more FEMA remapping efforts within the next five years.
The most current FIS along with the related FIRMs can be found below.
